## Answers ( )

Answer:Sine and cosine

Explanation:Velocity is a vector, so it can be resolved into two components into two perpendicular direction.

Generally, we take the x- and the y- direction of the cartesian plane.

If call v the velocity vector, then the components of the velocity along the two directions are:

where is the angle between the direction of the velocity and the x-axis.

Therefore, the resultant velocity can be found from its components by re-arranging the two equations above:

Therefore, the two functions that are used are the sine and the cosine.
